Abstract
En anordning for bruk i en brønnboring inkluderer generelt en strømningsrørkanal og en struktur som avgrenser et snirklet fluidløp nær strømningsrør-kanalen, hvor det snirklete fluidløp mottar en strøm av fluid. Det snirklete fluidløp er avgrenset av i det minste første og andre organer av strukturen, og de første og andre organer er bevegelige i forhold til hverandre for å justere et tverrsnittsstrømningsareal av det snirklete fluidløp.A device for use in a wellbore generally includes a flow pipe passage and a structure defining a coiled fluid passage near the flow pipe passage, where the coiled fluid passage receives a flow of fluid. The coiled fluid barrel is defined by at least first and second means of the structure, and the first and second means are movable relative to each other to adjust a cross-sectional flow area of the coiled fluid barrel.
